ROD OR PIPE SUPPORTING DEVICE.

Specification of Letters Patent.

Patented Aug. 29, 1916.

Application filed April 1, 1916. Serial No. 88,390.

to provide apparatusof the above mentioned.

character, which is simple in construction, strong, durable, andconvenient in use.

Other objects and advantages of. the invention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame, Figure 1 is a.

side elevation of apparatus embodying the invention, Fig. 2 is a planview of the same,

and, Fig. 3 is a horizontal sectional View taken on line 33 of Fig. 1.

In the drawings, wherein for the purpose of illustration is shown a.preferred embodiment of my invention, the numeral 5 designates apreferably cylindrical body portion of the apparatus, provided withhorizontal preferably diametrically arranged trunnions 6 carrying platesor washers 7, held thereon by means of bolts 8. Pivotally receiving thetrunnions 6 are U-shaped straps 9 for connection with a support,vertically movable carriage or the like. The body portion 5 is providedwith a vertical radially extending opening or recess 10, extendingthrough the side thereof, as shown. Atranged above and below the bodyportion 5 are circular plates 11 and 12, attached thereto by meansofbolts 13, as shown. The plates ll and 12 are provided with radiallyextending openings 14 and 15, forming in effect a continuation of theopening 10, as shown. The upper plate 11 is provided with an.enlargement or boss 16. to contact with a sleeve 17 carried by a rod 18,extending through the opening 10 and being supported. The means toprevent the lateral movement of the rod 18 out of the opening 10 iscarried by the bottom plate 12, and comprises curved jaws 19, operatingwithin curved grooves 20. The jaws 19 have their free ends beveled, asshown at 21, to contact with the rod'18, to permit of the rod passinginwardly beyond the jaws but these jaws prevent the outward movement ofthe rod, as is obvious. Pivotally connected with the opposite ends ofthe curved jaws 19, as shown at 22, are levers 23, the inner ends ofwhich are pivoted to the plate 12 within a recess 25, as shown at 24.The

levers 28 are moved apart or spread by a spring 24, attached thereto, asshown at 25.

From the foregoing description it is obvious that-the rod may beinserted by a lateral movement thereof within the open ing 10 and uponcontacting with the beveled ends 21 of the jaws 19 will automaticallyspread the same, until the rod passes inwardly beyond them. The spring24 will then automatically return the jaws 19 to the holding position.The rod 18 is supported I by the sleeve 17, contacting with the boss 16.The rod 18 is removed from the opening 10 by the operator moving thelevers 23 toward each other, which serve to spread the beveled ends 21of the jaws 19.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claim.

Having thus described the invention, 1 claim z In apparatus of thecharacter described, the combination with a body portion having alaterally extending recess and provided upon opposite sides withtrunnions, straps pivotallv receiving the trunnions, a plate mountedupon the upper end of the body portion said plate being provided with alaterally extending recess, a boss mounted upon the upper side of theplate, a, plate secured to the lower end of thebody portion and havingalaterally extending recess and provided upon its inner side with curvedgrooves, longitudinally curved jaws mounted In testimony whereof I afiixmy signature in presence of two witnesses. 1
